WRITING UTENSIL
Document Type and Number:
WIPO Patent Application WO/1997/044200
Kind Code:
A1
Abstract:
A writing utensil in which a tip receiving therein a rotating body adapted to be biased by a coil spring in an application tool for correction of wrong character or a ball-point pen to contact with an inwardly facing tip edge is connected through a point holder to an ink tank storing an ink adapted for solid-liquid separation, and the rotating body is caused to recede from the inwardly facing tip edge against the bias of the coil spring, thereby permitting an ink for solid-liquid separation to discharge and transfer. Arranged in a point holder (4) is a piece (7) integrally formed from a cylindrical portion (7-1) provided inside and in close contact with an inner surface of the point holder (4), a plurality of support arms (7-2) progressively inclined forward from a front end opening edge (7-10) of the cylindrical portion (7-1) in a substantially conical manner, and a spring bearing portion (7-3) provided contiguous to forward ends of the support arms (7-2) and supported coaxially to face forward. A pen point is left facing upward, whereby it is possible to return to an ink tank (1) an ink (2) for solid-liquid separation remaining in a tip (6) and the point holder (4) via an ink flowing port (12), which is widely opened with an opening area extending between the support arms (7-2) of the piece (7) and at least from a rear end of the spring bearing portion (7-3) to a forward end opening edge (7-10) of the cylindrical portion (7-1).
